METEOROLOaiCAL AND BOTANICAL ABSTEACT, 

 FOR THE SPRING QUARTER, 1869. 



The mean in all cases is taken from the sums of the three daily registers, 

 and not from the maximum and minimum. 



The dii-ection of the wind is registered from currents moving at a height 

 of 192 feet, and the force according to Lind's Wind Guage. The supposition, 

 however, of a uniform velocity during the month is a very arbitrary one, 

 and the results can be considered only ajDproximately correct. 



The relations of the quantities of rain which fell under the different winds 

 are registered each evening at sundown. 



The twenty-five years' standard tables are used for obtaining the difference 

 from the average.
